Parameters

source_bucket (str) – The source Google Cloud Storage bucket where the object is. (templated)
source_object (str) – The source name of the object to copy in the Google cloud storage bucket. (templated) You can use only one wildcard for objects (filenames) within your bucket. The wildcard can appear inside the object name or at the end of the object name. Appending a wildcard to the bucket name is unsupported.
destination_path (str) – The sftp remote path. This is the specified directory path for uploading to the SFTP server.
keep_directory_structure (bool) – (Optional) When set to False the path of the file on the bucket is recreated within path passed in destination_path.
move_object (bool) – When move object is True, the object is moved instead of copied to the new location. This is the equivalent of a mv command as opposed to a cp command.
gcp_conn_id (str) – (Optional) The connection ID used to connect to Google Cloud.
sftp_conn_id (str) – The sftp connection id. The name or identifier for establishing a connection to the SFTP server.
impersonation_chain (str | Sequence[str] | None) – Optional service account to impersonate using short-term credentials, or chained list of accounts required to get the access_token of the last account in the list, which will be impersonated in the request. If set as a string, the account must grant the originating account the Service Account Token Creator IAM role. If set as a sequence, the identities from the list must grant Service Account Token Creator IAM role to the directly preceding identity, with first account from the list granting this role to the originating account (templated).

execute(context)[source]¶

This is the main method to derive when creating an operator.

Context is the same dictionary used as when rendering jinja templates.

Refer to get_template_context for more context.
